Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Evaluation of Temperature Plume Distance under Effects of Groundwater Flow on Borehole Heat Exchanger

open access: yesZhileng xuebao, 2014
In the ground source heat pump (GSHP) system, the temperature around the borehole heat exchangers (BHEs) would continue to spread further with running time, in addition the groundwater flow would have an important impact on the thermal dispersion.

Bioinspired Janus Evaporator for Efficient Desalination of Saline‐Alkali and Seawater Through Photothermal‐Capillary Effects

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work combines textile technology to ingeniously integrate a hydrophobic PP/MXene photothermal sheath with a hydrophilic cotton core into functionalized yarns, successfully developing a Janus core‐sheath evaporator (PM‐CSY‐F). The evaporator demonstrates outstanding evaporation rates and efficient desalination efficiency when applied to treating ...

Anticipating Climate Change Along the Land–Sea Continuum: Why Policy and Organisational Dynamics Matter

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT How the organisational dimension of public policy influences climate change anticipation is a critical, yet underexplored, question. This is especially so at the local scale where many climate‐related interests are brokered. In this article, we argue that any analysis of the influence of de‐centralised organisations on climate change ...

Unravelling the Policy‐to‐Implementation Gap: Climate Adaptation Governance Arrangements in Medium‐Sized Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Urban areas are increasingly facing climate‐related risks that outpace the implementation of adaptation measures, often attributed to a persistent policy‐to‐implementation gap. Bridging this gap requires a deeper understanding of the underlying governance dynamics.

Enhancing Energy Efficiency and Reducing Emissions in the Textile Industry of Bangladesh: A Pathway to Sustainability

open access: yesEnergy Science &Engineering, EarlyView.
The study shows how major energy consumption in different sectors of Bangladesh's textile industry, driven by conventional electric motors, can be reduced by adopting Variable Speed Drives (VSD) and High‐Efficiency Motors (HEM). VSDs lower energy use through speed reductions of 20%, 40%, and 60%, while HEMs improve efficiency under motor loads of 50 ...
